Application filed May 3, 1915. Serial No. 25,385.

T0 all whom t may concern:

Be it known that I, CHARLES 7. Huis- BARD, a citizen of the United States, residing at Boston, county ofSufl'olk, State of Massachusetts, have invented an Improvement in Spinning and Twisting Apparatus, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to spinning and twisting apparatus of that type adapted to wind Iyarn in a yarn mass in layers extendin'g transversely to the axis of rotation, and the object of the invention is to provide a novel machine of this type in which all reeiprocating parts are eliminated so that the only motion which any of the parts have is a rotary motion; By thus eliminating all reciprocating motions and using only parts which have a rotary motion a device is piof vided which will run at a very high speed without any jar or vibration and by which the yarn produced will be even and uniform in size.

Iii order to give an understanding of my invention I have illustrated in the drawings a selected embodiment thereof which will now be described, after which the novel features will be pointed out in the appended claims.

Referring now to the drawings, Figures l and 2 are veitical sectional views through a winding and twisting head embodying iny invention, said views being taken at right angles to each other, Fig. 1 being taken on substantially the line www, Fig. 3, and Fig. 2 on the line 1j-y, Fig. 3;

Fig. 3 is a section on the line www, Fig. 1;

Fig. 4 is a section on the line Z-Z), Fig. 2.

My apparatus is of that type involving` a yarn receiver adapted to receive the yarn mass being wound, a winding plate which rests onone end of the yarn mass and has a rotary movement relative thereto and means for traversing the yarn radially as the winding plate rota-tes thereby to lay the yarn in layers extending transversely to the axis of rotation.

' The? yarn receiver may have any suitable or usual construction and is shown more or less :diagrammatically at 1, said yarn' re- ,ceiver' being. mounted Iorv rotation and Aadapted to receive a yarn mass 2. rIhe winding plate is shown at 3 and it rests on' one end of the yarn mass and is provided with a radial slot 4 through which the yarn 5 is` delivered. This winding plate 3 is rotatably mounted, as usual in machines of this type, but it rotates at a different speed than the yarn mass andyarn receiver so that a winding or yarn-laying action will take place due to thc relative movement of the winding plate and yarn receiver.

In devices of this type as heretofore constructed an oscillatory yarn guide has been employed for traversing the yarn back and forth in the slot. By my invention I eliminate this oscillatory element and substitute therefor a rotary element.

The winding plate 3 is herein shown as sustained on a shaft G which is driven by a suitable gear 7, said shaft being hollow so that the yarn may pass down through it from a source of supply.' rlhe yarn guide bv which the yarn is traversed in the slott is iii the foi'in of a rotary cam element 8 l which rotatesl relative to the winding element. Associated with the yarn guiding or traversing member S is a compensating member 9 also in the form of a cam which is rigid with the member S. The yarn 5 passes down through the hollow shaft G, out through the opening l0, and around one edge of the member 9, thence to the' opposite edge of the yarn-guiding member '8, and thence through the slot 4 to the yarn mass 2. A suitable guiding element 11 is' associated with thc compensating element 9 with which the yarn has engagement and which holdsthe yarn in proper position onithe increasing amount of slack there-in as they yarn-laying element 8 lays the yarn in toward the center of the yarii mass or toward the inner end of the slot 5, said element 9 operating to give up the slack in the yarn as the point at which the yarn is being laid moves outwardly toward the outer end of speed rethe slot 4. The yarn will thus be drawn' through the tube with an approximately uniform movement.

rthese two 'ar11-controlling elements 8 and S) may be given their rotary motion in any desired way. I have herein shown a construction wherein their rotary motion is derived partly 'lrom the rotary motion of the shaft t3 and partly from the rotary motion ol a second shalt 12 through which .the shaft 6 extends, said shaft 12 being driven by a suitable gear l?) at a ditl'erent rate ot speed from that ot the shat't (3. The shat't (S is shown as having rigid therewith a. housing.)` or casing 14 in which is mounted a, shaft 15 farrying at its upper end a `gear 1G meshing with a gear 17 tast on the shaft 12. The shaft 15 carries at its lower end a pinion '18 which meshes with a gear 19 'tast on a sleeve 2() that rotates t'reely about the shaft (5 and to which the eleinents S and 9 are tixedly secured. TheI gears 1T and 12) have a different number of teeth thereon, andsince the housing 14 with the shat't 15 rotates bodily with the. shaft o the differential movement between the shafts 12 and (i will operate tln'ough the gearing` above described to give the yaril-controlling elements 8 and 9 a rotation at a diti'erent speed from that 'ot the winding plate 3. This housing 14 ispreterably made oil-tight so that the gears may run in oil and as all of the parts of the device are rotary parts and no reciprocating parts are employed. the device may be operated at a high speed without producing any undesirable `iar or viln'ation. .Moreover, as tln` compensating element S) operates to compensate t'or the in-andout traverse ot the yarn, said yarn will be drawn through the shaft (i trom the source of supply at an approximately even rate of speed, thus obviating any possibility (if breakage ot yarn due to an uneven feed. i

I have shown at 21 an anti-friction bear- A ing between the gar 17 and the central or hub portion of the housing 14, the purpose of which being to reduce friction.

It will be understood, of course, that provision will be made so that as the thread mass 2is built up the winding plate with its associated mechanism will rise or the thread mass will be depressed. I have not shown in the drawings any provision for this as it forms no part ot the present invention.

While I have illustrated herein a selected embodiment of the invention, I do n0t-wish to be limited to the constructional features shown. l
